Oh yeah Alshar, I remember opening the third map first because I was so clueless before with custom levels and with Alshar itself having the issue of map 1 mysteriously missing (or not loading? I forgot).

That said the boss area is quite the icon of the earliest custom mapping.

This is a really short map without too much in it beyond a standard Warlord boss fight. Still, given this was one of the first Unreal sets ever, stuff like the collapsing bridge/water current and Nali moment at the end were somewhat impressive moments.
